MIDDLINGS-PURIFIER.

SPECIFICATION forming part of Letters Patent No. 350,385, dated October 5, 1886.

Application filed March Q5, 1886.

To all whom it may concern.-

-Bc it known that I, UDoLPHo H. ODELL, aresident of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Middlings-Purifiers, of which the following is a specification. f

My invention relates to that class of middlings-puritiers which employs either asuction or force blast to assist in purification. I have illustrated the application as employing a suction-blast fan; but I do not wish to limit myself to the use of the suction-blast, as my invention is equally adapted to be used in any well-known form of .purifying-blast.

One of the principal objects of my invention is to provide suitable means to keep the screencloth clean, or to prevent the iiuff from being caught in the mesh of the cloth of apurifieror separator.

Another object of my invention is, in addition to cleaning the cloth, to-present the middlings or stuff operated upon by the riddle to the action of the air-blast, so as to carry oii the fluffy matters, all of which will be fully set forth in the description of the accompanying drawings, making a part of this specification, in which .v

Figure l represents my improvement attached tothe oase ofa middlings-puriiier. Fig. 2 is a longitudinal verticalcentral section of the same. Fig. 3 is a top plan View of the riddle-cleaning device.

A represents the frame of thepurifier; B,the blast-chamber; C, the fan; D the riddle-frame; E, openingsfor the admission of air into the purifying-chamber; F, feed-opening; G, feedspout; H, cross-arms-of theriddle-frame; I, an

eccentric for shaking the riddle.

K represents spring shaker-bars, the ends of which are attached to the frame of the purifier. L represents a bolt attaching the spring-bars to the riddle. These bars spring enough to allow the riddle to have a reciprocating motion. I do not wish to limit myself to the method herein shown of suspending the riddle-frame, as any well-known form may be employed in lieu of the devices herein shown and accomplish the principal purposes of my invention. a represents sprocket-wheels. b represents a sprocket-chain traveling thereon'.

Serial No. 196,553. (No model.)

c represents thecloth attached lo the under Aside of the riddle-frame.

d represents a series of stationary slats or arms attached to a rectangular frame, e. These A ried around over the sprocket-wheels and under the riddle-frame, as shown in Fig. 2.

represents a series of balls, preferably made of rubber, attached to a string, which is preferably made of rawhide or other tenacious substance. The strings are secured to thebar h, and the balls at the free ends of the strings o. As the bar his drawn across, the balls strike the slats (l and rebound up and strike the cloth l c and drop down and strike the ends of a succeeding rail d, which again causes the ball to rebound and strike against the cloth. Thus a continual intermittent striking ot' the balls against the cloth is obtained as the bar h is drawn across under the riddle-frame.

I do not wish to limit myself to the use of balls, asany weighted matter attached to the free end of a flexible cord which is secured to the bar It may be used to secure the knocking or striking action against the cloth as the bar h is drawn across under the riddle-frame. This action of the balls is very important, asvthc sharp blow beatsor knocks the fluff out of the cloth should any be lodged therein; but these knockers also perform a moreimportant function. The blowstrikingagainstthe cloth throws the middlings or stuff resting on the screen up and subjects the stufi'so elevated to the action of the air-blast, which carries off the fluff and into the meshes of the separating-cloth.

This device may be used with any known form of purifier, and it is much superior t0 the cloth-cleaners hitherto employed for this purpose.

The shape and form of the rails or stops cl may be variously modiiied. I deem wooden slats set a ysufficient distance apart to allow the air to pass up between them to be the cheapest .in a great measure prevents it from settling IOO and best; but any arrangement or form of stops with air-spaees between them may be employed in lieu of the slats Z here shown, the object being to furnish a movable obstacle, against which the balls hit as they are dropped by gravity and rebound against the cloth, so as to throw the stuff up and Subj eet it to the action of the air-blast.

Having described my invention, what I elailn as new isl. In a purifier7 the Combination, with an agitating-riddle having a separating-cloth, of the frame e, having a series of stops, d, an endless belt provided with a erossbar, 71, and a series of lexible knookers `attached to said bar, substantially as described.

2, In a purifier, the combination ofa riddle,

and the slats, whereby the knoekers are inade to strike intermittently against the eloth, sul stnntially as specified.

In testimony whereof I have hereunto set lny hand.
